UNHTED STATESP ATENT GEORGE ROTTMAN, OF NEW YORK, N. Y., ASSIGNOE TO RUSE'JLH CORPORATION, OF BROOKLYN, NEW YORK, A CORPORATION OF NEW YORK.

IDUS'I'PROOF AND ItIOTHPROOF BAG.

. Application filed October 9, 1920, Serial No. 415,925. Renewed may 7, 1923.

T 0 all whom it may con cern Be it known that I, GEORGE RoTrMAN, a citizen of the United States, residing at 252 Broome Se, city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in a Dustproof and Mothproof Bag, of which the following is a specification.

My invention relates to a new and improved construction of dustproof and moth- -proof bag. 7

Bags of this character have been well known for a number of years and are extensively' used for holding clothes during the summer time for preventing them from being injured by dust and moths.

For convenience in storage and shipping, these bags have been so constructed that they could be collapsed into the flat condition. As a result thereof, when these flattened bags are opened out into their extend ed position and the clothes were put into the bags, and the bags were then hung upon a hook in the usual manner, they tended to collapse into their fiat condition so that the clothing became wrinkled and had to be repressed at the end of the summer.

The object of my invention is to produce which can be readil collapsed and whic has a dGfiIIllB'bOX-llkfi structure or shape when it is used.

Other objects of my invention will be disclosed in the following description and drawings which illustrate a pre erred embodiment thereof.

Fig. 1 is a perspective view of my be in the operative or extended position, an before the top thereof is closed.

Fig. 2 is a top view of Fig. 1.

Fig. 3 is a detail view showing the bag partially collapsed.

Fig. 4 illustrates how the bag is closed so as to prevent the entrance of dust and moths.

Fig. 5 is a side view partially in section showing how the'bag is closed.

The bag is made of paper or the like and is creased along the lines 2, 10, 11, 12,14,-

Fach side of the bag has pasted or otherwise secured thereto an innerfiap 5, which is preferably centrally creased so as to correspond to the central crease 2 of each side.

This flap 5 can be held in the position these three layers together.

shown in Fig. 3 so as to permit collapsing of the bag or it can be moved up into a position parallel to the bottom of the bag as illustrated in Fig. 2.

When the clothing has been hung upon the inner end of the hook 6 which extends into the interior of the bag according to the wellv known construction and which is secured to the bag in any suitable manner, the bag is closed as follows:

, The flaps 5 which are hingedly connected to theside of the bag above the hook 6, are moved into their operative position, parallel to the bottom of the bag. These flaps can be made of the same kind of paper as the top of the bag or of stifl'er material if this is desirable.

The bag is now folded along the upper diagonal creases 14: until the front and back of the bag meet at the top. The top of the bag is now folded along the three top creases 10, 11, 12, this folding being in alternate directions, so that the three top sections of the bag now form three closely adj acent layers. 7

The hook-like fastening means 3 which are slidably mounted upon studs 4 secured to the rear of the bag are now slid inwardly or toward each other so as to firmly hold The be can now be hun u b means of hook 6. g p y Experience has shown that if the flaps 5 are omitted in a bag having a construction till otherwise identical with that herein illustra-ted, that when the bag is suspended from its hook that the sides thereof bend internally so that the bag becomes collapsed and the clothing becomes badly wrinkled.

The flaps 5 constitute a very cheap, simple and eficient means for preventing t is.

I have described a preferred embodiment of my invention, but it is clear that numerous changes and omissions could be made without departing from its spirit.

I claim:

1. A dust-proof bag comprising a body portion and a top closure portion which extends above said body portion when the bag is open, said portions being so creased that the entire bag can be folded flat, means for keeping the top closure portion in a closed and folded position, and flaps secured to the till llllll sides of the said he in a hinge-like manner below the mouth 0 said bag. the said flaps being creased so that they can be folded.

when the bag is collapsed into the flat condition, the said flaps being capable of being extended into positions substantially 2. A dust-proof bag having a body por-.

tion and a top closure portion, the sides of the said bag bein provided with central crease lines, and a so with diagonal crease lines at the bottom and at the top of the said body portion, the said closure portion being provided with three continuous and parallel crease lines which extend around the four sides thereof and are substantially at right angles to the central crease lines of the said sides, means for maintaining the said closure portion in a closed and folded condition, and flaps secured to the said sides in a hinge-like manner below the mouth of said bag, whereby the said flaps can be bent downwardly so as to be parallel to the said sides or can be bent upwardly so as to be motors perpendicular to'the said sides to lreep the said body portion in extended position.

3. A dust-proof bag having a body portion and a top closure portion, the sidesot the said bag bein provided with central creaselines, and a so withdiagonal crease lines at the bottom and at thetop of the said body portion, the said closure portion being provided with' three continuous and parallel crease-lines which extend around the four sides thereof and aresubstantially at right angles to the central crease lines of the said sides, means for maintaining the said closure portion in a closed and folded condition and flaps secured to the said sides in a hinge-like, manner below the mouth of said bag, whereby the said flaps can be bent downwardly so as to be parallel to the said sides to keep said body portion in extended position, the said means consisting of clips, slidably secured to the rear of the said closure portion at the top-thereof.

In testimony whereof I hereunto afiix my signature.
